, 2014 BAR superfamily proteins have a banana-shaped domain that causes the local bending of lipid membranes. We study as to how such a local anisotropic curvature induces effective interaction between proteins and changes the global shape of vesicles and ...

Wild pig habitat use impacted by prescribed fire in the William B. Bankhead National Forest, USA
The Journal of Wildlife Management, EarlyView.Natural resource management activities like integrated wild pig control programs and 3–5‐year interval prescribed burning can reduce wild pig activity and habitat but can have an unintended side effect of allowing them to thrive in sensitive and protected areas, where access and tools are restricted.

Structural Concrete, EarlyView.Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.Abstract The fossil record of coelacanths (Actinistia) is diminished by several nominal gaps that obscure vital information pertaining to the clade's evolutionary history. Latimeriidae, the family that includes the extant coelacanth Latimeria, in addition to the Cenozoic, has an outstanding missing gap of 50 myr during the Mesozoic, with no records of ...

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990 In order to avoid the influence of the displacement of gear axes under load upon tooth contact, the authors propose that a projective group of the surface normals should be concentrated upon the intersection point of the plane perpendicular to the wheel axis and the axis about which the worm axis rotates, displacing its position relative to the wheel ...

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.Abstract The Late Cretaceous witnessed numerous transgression–regression sequences and the onset of a global cooling phase at the start of the Campanian. In the European archipelago, these environmental changes, combined with active plate tectonics, facilitated the formation of ephemeral land bridges that served as dispersal routes for a variety of ...

Mechanism of CO2 and NH3 transport through human aquaporin 1: Evidence for parallel CO2 pathways
The Journal of Physiology, Volume 604, Issue 1, Page 336-365, 1 January 2026.Abstract figure legend The figure illustrates the permeation pathways for CO2, NH3 and H2O through AQP1. The panel on the left, with the wild‐type protein under control conditions, CO2 moves through monomeric pores (2 of 4 shown) but predominantly via an alternate pathway (perhaps the central pore of the tetramer).

Jixie chuandong, 2017 At present,the problems of the poor accuracy and low efficiency etc exist in the solar tracking system,one of the main reasons is that the hourglass worm drive pair is not the right conjugating transmission form.
